I logged into a server that supports the Customizable Player Models mod, and those who already have this mod on the server do not see my model, although I see my model myself. I disabled the profile in the security settings, but it didn't help me, so he also writes that "Your in-game UUID is incorrect, the server is probably offline. Models may not load.". However, I saw another person's model, which is very strange. Help me figure this out

cpmmodels without UUID lock will load, skin encoded or UUID locked models won't.
